Frames Returned by peekdata

Note: The peekdata function does not return any data while running if in disk logging

mode.

The following example illustrates how to use peekdata:

Create an image acquisition object — This example creates a video input object

for a Data Translation image acquisition device. To run this example on your system,

use the imaqhwinfo function to get the object constructor for your image acquisition

device and substitute that syntax for the following code.

vid = videoinput('dt',1);

Configure properties — For this example, configure a manual trigger. You must

use the triggerconfig function to specify the trigger type.

triggerconfig(vid,'manual')
